  由四烷基铵客人精调基于阴离子的三螺旋结构的弹簧运动

  摘要：

  超分子弹簧是一类分子装置，可从分子水平上对宏观弹簧的行为产生影响。螺旋结构是合适的分子弹簧，因为螺旋线的特定扭曲会在外部刺激下引起沿轴的弹簧状（伸展-收缩）运动。在此，我们报告一个基于阴离子的三螺旋弹簧，该弹簧可以通过引入和除去四烷基铵阳离子（包括TMA +）进行可逆的伸缩运动。与类似的不规则四面体阳离子带有不同的烷基链，而两个磷酸根离子的相对方向发生变化以利于客体夹杂。值得注意的是，可以通过改变客体阳离子的形状和大小来微调收缩度（缩短螺距）。但是，使用较大的阳离子（TEA +，TPA +和TBA +），可获得中螺旋结构，可通过添加/去除TMA +离子与螺旋结构互变。

  Crystal Structures of Two Complexes of the Rare-Earth-DOTA-Binding Antibody 2D12.5:  Ligand Generality from a Chiral System

  摘要：

  We report the crystal structures of antibody 2D12.5 Fab bound to an yttrium-DOTA analogue and separately to a gadolinium-DOTA analogue. The rare earth elements have many useful properties as probes, and 2D12.5 binds the DOTA (1,4,7,10-tetraazacyclododecane-N,N",N",IV""-tetraacetic acid) complexes of all of them (Corneillie et al. J. Am. Chem. Soc. 2003, 125, 3436-3437). The structures show that there are no direct protein-metal interactions: a bridging water acts as a link between the protein and metal, with the chelate present as the M isomer in each case. DOTA forms an amphipathic cylinder with the charged carboxylate groups toward the face of the chelate near the metal ion, while nonpolar methylene groups from the macrocycle and the carboxymethyl groups occupy the rear and sides of the molecule. The orientation of the metal-DOTA in the 2D12.5 complex places most of the methylene carbon atoms of DOTA in hydrophobic contact with aromatic protein side chains. Other binding interactions between the metal complex and the antibody include a bidentate salt bridge, four direct H-bonds, and four to five water-mediated H-bonds. We find that 2D12.5 exhibits enantiomeric binding generality, binding yttrium chelates in both Delta(deltadeltadeltadelta) and Delta(lambdalambdalambdalambda) configurations with modestly different affinities. This develops from the symmetrical nature of the DOTA chelate, which places heteroatoms and hydrophobic atoms in approximately the same relative positions regardless of the helicity of DOTA.

• Room-Temperature Copper-Catalyzed Carbon-Nitrogen Coupling of Aryl Iodides and Bromides Promoted by Organic Ionic Bases

  solubility alone does not explain the performance of organic ionic bases in the room‐temperature coupling of aryl iodides and even bromides with aliphatic and aromatic amines and N‐heterocycles (NuH; see scheme). Conductivity measurements show that these organic ionic bases, which contain tetraalkylammonium or ‐phosphonium cations, are readily ionized in organic solvents.

  An anion‐coordination‐based A4L6 (“A” denotes anion and “L” is ligand) tetrahedral cage was constructed by a C2‐symmetric bis‐bis(urea) ligand and phosphate anion, which showed reversible interconversion with the A2L3 triple helicate as a response to the template, concentration, or solvent. Notably, an unusual “peripheral” templation was found to be critical to stabilize the tetrahedral structure.

• Anion-Coordination-Driven Assembly of Chiral Quadruple and Single Helices Controlled by Countercations

  Enantiopure helical assemblies were constructed by chiral C2-symmetric bis-bis(urea) ligands (LS/R) with phosphate or hydrogen phosphate anion, which is dictated by the countercation. In the presence of smaller cations (TMA+ or TEA+), the chiral ligands coordinate to dihydrated phosphate to form homochiral quadruple helicates (TMA)6[(PO4·2H2O)2LS/R4]. However, when larger cations (TPA+ or TBA+) were used, the ligand tends to assemble with monohydrated hydrogen phosphate ions into infinite single helices (TPA)2n[(HPO4·H2O)LS/R]n or (TBA)2n[(HPO4·H2O)LS/R]n. The predisposed point chirality next to the anion binding center in the ligands has a profound impact on the resulting assemblies, and their chirality is manipulated in a predictable manner.

  手性 C2 对称双（脲）配体（LS/R）与磷酸或磷酸氢阴离子构建了对映纯螺旋组件，这是由反阳离子决定的。在较小的阳离子（TMA+ 或 TEA+）存在时，手性配体与二水磷酸配位，形成同性四螺旋体 (TMA)6[(PO4-2 )2LS/R4]。然而，当使用较大的阳离子（TPA+ 或 TBA+）时，配体倾向于与一水磷酸氢根离子组装成无限单螺旋体 (TPA)2n[(HPO4-H2O)LS/R]n 或 (TBA)2n[(HPO4- )LS/R]n。配体中阴离子结合中心旁边的预设点手性对所产生的集合体有着深远的影响，而且它们的手性是以可预测的方式操纵的。
